DRYING APPARATUS FOR BRlCIK AND TlLE KlLNS.

SPECIFICATION forming part of Letters Patent No. 311,557, dated February 3, 1885.

Applicaiion filed June 9, 1884. (X0 model.)

To all whom, it may concern:

Be it known that I, Onnsrnn L. Aims, a citizen of the United States of America, residing at Cabery, in the county of Ford and State of Illinois, have invented certain new and useful Improvements in Drying Apparatus for Brick and Tile Kilns, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a side View with certain portions broken away to show the interior, and Figs. 2, 3, and 4, cross-sectional views of the fines for conducting the escaping heat from the kilns to the dry-house and from thence to the chimney.

This invention consists in a device for utilizing the waste and escaping heat and gases from a brick or tile kiln for drying the green tile or brick in the dry-house adjacent to but disconnected from the kilns for safety.

Heretofore it has been the usual practice to erect the kilns in the dry-house, or in abuilding in which all the other works and machinery are located, and in which the brick or tile in their green state were placed to dry 011 floors above the kilns, for the purpose of ntilizing the heat emanating from the exterior surface of the kiln. This arrangement is always fraught with great danger from the liability of the kilns to fire the building, and not very effectual for the purpose of drying the green tile or brick on account of the limited amount of heat from the kiln-walls.

The object of this invention is to provide means for conducting the waste heat from the kilns to a dry-house to heat it, and then escape to a chimney, and thus render it practicable to locate the dry-house a far enough distance from the kilns to be safe from danger of fire.

Referring to the drawings, H is the dryhouse, of any pattern or design desired to suit the purpose for which it may be used. K and K are the kilns; G, a chimney, and P a flue extending from the chimney under the dryhonse to near its farther side from the chimney, and, after making a circuit of the building, passes out and divides into two branches, P and P, the branch flue P passing under the kiln K to a chamber about the center of the kiln-such as is shown at Z in kiln K-the flue P entering one side of said chamber, and the flue P passing on from the other side of said chamber to the chimney. Flue ll? passes in like manner under kiln K to the chamber Z, and flue P passes from said chamber on to the chimney 0. These chambers Z form openings in said fines for the heat and smoke from the kilns to enter said lines. The furnaces are shown at n, and they are so constructed that the heat must ascend in front of a closed back, and then descend through the loosely-laid tile or brick to the chambers Z, and from thence into the fines just described. Dampers a and a are located, respectively, in the fines P and 1?, between the kilns and the chimney. Vthen they are open, a direct draft passes from the kilns up the chimney without entering the dry-house flue. hen closed, the draft will be through the dry-house flue around to the chimney. The arrows show the course of the drafts. Dampers a and a are placed, respectively, in the fines P and P, between the kilns and the juncture of said two fines, for the purpose of regulating the supply of heat to enter the dry-house, or shutit oil altogether, if desired.- Thesefluesareallintendedtobeplaced in the ground, to be at or below the surface to be out of the way, and to render them more capable of retaining the heat. A cross-section of the flues is shown in Figs. 2, 3, and 4, and may consist of a trench, R, having side walls, as shown in Fig. 2, without side walls, as shown in Fig. 3, or with metal walls, as shown in Fig. 4; or they may be any construction that will answer the purpose. The portion of the flue that is located under the dry-house H is constructed so as to permit the escape of heat, but notof the smoke. This is accomplished by covering the line at the surface of the ground with a thin cover or plate of metal, 11, which is in turn covered and protected by the brick or metal arched roof It, pierced with holes h, for the escape of the hot air into the dryhouse, as shown in Fig. 1, for the purpose specified. By this means no fire is used in the dry-house, and the heat from the kilns, that is to a very great extent wasted, is used to initially dry the tile, brick, &c., before it is placed in the kilns. The kilns are isolated from the dry-house, and any number of kilns may be used and thus connected with the dry- 5 house.

Having-thus described my invention, What I claim as new, and desire to secure by Letters Patent, is as follows, to wit:

1. Theoombination of theflueP, having the '0 thin metal plate or cover 2) and arched cover R, grovided with the perforations h, sewers I? P P P, having the dampers a a a a and kilns K and K, having the chambers Z, all

1 perforated arched cover R, and means for conducting the escaping heat from detached kilns K and K through said flue, as and for the 20 purpose set forth.
